Oh great thanks do I add fish on day one of just upswing Dr Tim’s one and only if so what fish do you recommend ?Dr. Tims sells a fishless cycle kit if your not sure on dropping in a fish right away. I plan on dropping in a fish on day one as they are the ammonia source . Just gotta check your water daily. Of course everyone has their own opinions and im just spouting someone elses experience and advice though they are a professional. Look up some of the BRS vids and the starting series from Saltwater Aquarium.com on youtube.
